SANGAKU

For Sudoku aficionados, math lovers, and puzzle worshipers -- a whole new world of number fun inspired by ancient Japanese riddles!

SANGAKU is the captivating new number game that uses simple math and logic to reveal the mystic harmony and powerful symmetry of numbers. Japanese for “mathematical tablet,” SANGAKU puzzles are named for ancient devotional tablets featuring complex geometry problems left in temples and shrines centuries ago. The puzzles in this book evoke the same feelings of awe for the mystery, complexity, and power of numbers that inspired the mathematicians and mystics of ancient Japan. These puzzles work a bit like Sudoku: the player is presented with a pattern, shape, or grid, and must put the correct numbers in the right spaces in order to complete the puzzle based on mathematical rules. BUT: SANGAKU puzzles force you to think outside the box — literally! They can be any size, shape, orarrangement, and may call on any set of numbers, not just zero through nine.But despite their limitless variety and unpredictable challenges, these puzzles require nothing more than basic math skills and elbow grease to complete. They are fun, they are addictive, and they keep the old noggin nice and nimble! With more than two hundred puzzles, SANGAKU guarantees hours of amusement, sharpened math skills, and a fresh new way to think about numbers. SANGAKU is perfect for puzzle lovers of every age and skill level. James D.Hill is a retired educator who taught math, physics, biology, chemistry, and science at the high school level.
